    A minimum load is required for the reliable operation of a rolling bearing. If the minimum load is not reached, slippage may occur. Tapered roller thrust bearings are protected against slippage exclusively through a minimum axial load. The calculation for the minimum axial load for tapered roller thrust bearings is shown in the following formula:

  • Tapered Roller Thrust Bearings | KRW Leipzig

    Bearing Design . Double row tapered roller bearings are separable and non-latching bearings. In addition to radial forces, they can, due to the mirror-image arranged bearing, also absorb high axial forces in both directions. For combined bearing sets there is a distinction between O-, X-, or tandem arrangement based on pressure line contact.
